Another less common method for producing immersive VR experiences uses stereoscopic projection screens arrayed around a user in various configurations. Sometimes six-walled projection rooms known as cave automatic virtual environments (CAVEs) are used that allow for interaction in a less encumbered, wide field of view simulated environment for multiple concurrent users. However, such CAVE systems are more costly and complex, and are typically beyond the practical resources of most clinical service providers and/or basic researchers.
Regardless of the technical approach, the key aim of these immersive systems is to perceptually replace the outside world with the virtual world to psychologically engage users with simulated digital content designed to create a specific user experience. Immersive VR (most commonly delivered in an HMD) is typically the choice for applications where a controlled stimulus environment is desirable for constraining a user’s perceptual experience within a specific synthetic world. This format has been often used in Clinical VR applications for PTSD and other anxiety disorder exposure therapy, analgesic distraction for patients undergoing acutely painful medical procedures, and in the cognitive assessment of users to measure performance under a range of systematically delivered challenges and distractions.
VR Exposure Therapy for PTSD
Think about the worst thing that ever happened to you and remember how you felt immediately afterwards. Now imagine that six months or a year later, you still felt that exact same way with the exact same intensity. That is PTSD and it has a
